RE: [Ltib] Problem using LTIB

[Daniel Brown]

Stuart,

Actually, I finally discovered the problem. The download wasn't finishing
due either to my network or to the server. The download transfer rates
were all over the place but at their worst were 1 KB/sec and the connection
was timing out. I guess the wgets program doesn't catch or send an appropriate
signal on connection termination but the script, thinking the file was
downloaded, probably did an MD5 checksum on a partially downloaded file.
I edited the wgets options to remove the non-verbose mode and improve 
the timeout of only 12 seconds. This did better but for some reason the
connections still timed out. There is something wrong with our network which
I am having IT look into. After several tries I was finally able to get
LTIB to download all the necessary RPMs and finish the compile.

Thanks for the help.
Daniel

Hi Daniel,

That is just for installation so you can run /mnt/ltib/install.  Make
when you run the installer you are in some area with local disk

Also, in the output I see the warning:

locking

If you can avoid running on an NFS area, you'll have less problems as
your IT department can setup all sorts of restrictions.

Finally the message:
>     ERROR: md5sum mismatch, re-naming
>     /opt/ltib/pkgs/tc-fsl-x86lnx-armeabi-nptl-4.1.2-3.i386.rpm to

This shows there was some kind of download error.  Can you take a look
at the .bad file (run file and see what it is, check the size).  The
idea is to see if the http server returned an error (which will be in
the .bad file).  One possibility is that you need to set up a web proxy
(does your browser use one?).  The other possibility is that the
download aborted for lack of disk space or some other reason (IT quota
policy etc?).

Regards, Stuart
